ill) all whom it may concern. Be it known that i, Gama Henna Menorah HAL ER, a citizen of the United 'ritates siding at Judaqin the county of Green and State of \"Visconsin have invented a new and useful '(heesc-Stirrcr, of which the following is a specification.

' This invention relates to stirring coparatus, and has especial reference to stirring apparatus used in the manufacture of cheese.

The invention has for its object to provide an improved apparatus of this kind by means of Which the contents of a. kettle will be thoroughly and effectively stirred, over and across the entire bottom of the kettle. The invention (1431"5SiS of a stirring apparatus of thecharacter referred to, constructed and arranged as hereinafter set forth and claimed. T

Referring to the drawing, Figure 1 is a View in elevation of an embodiment of the invention. a part of the kettle being broken. away. Fig. 2 is a detail plan View of a part of the stirring mechanism on the line w o Fig. 1.

In carrying out the invention a frame Work 1, is provided in which is mounted a crane 2, from the swinging arm?) of which; is suspended a kettle 4. The stirring mechanism consists of a tubular arm or sleeve 5 depending from the outer end of the arm 3 into the kettle 4E, and having its upper end extending through, and fixed to the end of arm 3. Extending through the tubular arm 5 is a rotary shaft 6 having a horizontal disk wheel 7 mounted on itsupper end and formed at its lower end with a laterally extending arm Sin the outer end of which is journaled the vertical bent portion 9 of a horizontally swinging arm 10, having at its outer end a depending arm 11 supporting the stirrer 12 adjacent to the side and bottom of the kettle 4. Upon the lower end or" thetubnlar arm5is mounted a fixed sprocket wheel 13, and on the vertical portion 9 of nected with the sprocket Wheel 1? by an endless chain 15. By means of the foregoing mechanism. when the shaft 6 is rotated, the arm 8 will he swung in a circle about the axis of shaft 6, and by this movement will cause the sprocket Wheel 14 to turn, owing to its connection by chain 15 with sprocket wheel 13. The wheel 1% being thus caused to fipecttleation of Letters turn will swing the arm 10 in a circle about,

the vertical portion 9, carrying h it the stirrer on arm 11. in these two movements of the arms 8, and 10 the stirrer will he moved in succession of circles over the bottom of the kettle between its center and its sides throughout the circumference of the kettle, thereby thoroughly and efi'ectirely stirring all. of the contents of the kettle extending over its bottom.

Any suitable mechanism may he used to operate the stirring mechanism, and preferahly the following is employed. Mounted in brackets 16 on the arm 3 is a shaft 3.? having mounted on its outer end 18 a friction dish 1.9 which rests on disk Wheel 7 and inrparts rotary motion tl'iereto. To change the speed of disk Wheel '7 and therchyimpar greater or less movement to the stirring mechanism, the friction disk 19 is made adjustable on the outer end of shaft 17. This is done here shown, preferably by makin the end 18 of shaft. 17 square and having the disk 19 slidahl-e thereon, the adjustment oeing effected by means of a handle 26 having a fiorircd end .21 engaging a collar :22 on the disk 19. The handle 20 is held in adiusted position. oy means of a rack 23 engaging a tooth or projection 2% on the bracket 16. The shaft 1? is operated by a bevel gear wheel on its'inner' end, which meshes with a bevel gear wheel 25 on the lower end other end of sha t, 31 being; connected by universal joint 38 with a. shaft 3-;t mounted in the upr ghts l of the frame 1, and carry ing a driving pulley 35. In order to ac connnodate the shaft to the swinging movement of the arm 3 of the crane when it is moved to shift the kettle to ditt'erent positions, the shaft 31 is made adjustable, the shaft lacing formed with a section 36 which projects into and is slidahle in a sleeved section 37, the sect ion 36 having lateral pins 38 which project through slots 35) in the sides of the section 37, and are connected with a sleeve 4.0. which is slidable on the sleeve section By means of the adjustable shaft 31, connected by the universal joint 33 with the shaft 34. the driving mechanism is automatically adjusted to the swinging movement of the crane;
